The Fitzpatrick Scale, or Fitzpatrick Skin Phototype, is a numeric classification of human skin types developed in 1975 by dermatologist Dr. Thomas B. Fitzpatrick. It categorises skin based on its reaction to ultraviolet (UV) light (particularly how likely it is to burn or tan) and remains widely used in dermatology for assessing skin cancer risk, photodamage potential, and optimising cosmetic and medical procedures.
How It Works
The scale classifies skin into six types (I–VI) based on:
Skin colour (ranging from very pale to deeply pigmented)
Response to sun exposure (likelihood of burning or tanning)
This helps professionals predict sun sensitivity, skin cancer risk, aging patterns, and treatment outcomes.
The Six Fitzpatrick Skin Types
Type I: Very fair, burns easily, rarely tans; common in Northern European populations.
Type II: Fair, burns easily but tans minimally; often of European or Northeast Asian descent.
Type III: Medium beige or pink, moderately sensitive, tans gradually; seen in Mediterranean, Latin American, Middle Eastern, Native American, or East Asian backgrounds.
Type IV: Olive or light brown, mild UV sensitivity, tans easily; common in East Asian, South Asian, African, Latin American, Middle Eastern, or Native American populations.
Type V: Brown skin, tans readily, highly resistant to sunburn; common among African, Latin American, Middle Eastern, Austronesian, Australian Aboriginal, or South Asian groups.
Type VI: Very dark brown, minimal sun sensitivity, rarely burns; found in African, Austronesian, Australian Aboriginal, or South Asian populations.
Why Skin Phototype Matters
The Fitzpatrick scale classifies skin into six types, though not every individual will fit perfectly into a single category. In such cases, select the type that aligns most closely with the skin’s characteristics.
Knowing a person’s skin phototype provides a valuable reference for what their skin can tolerate. This information is particularly useful when planning more intensive treatments, such as chemical peels, or when evaluating suitability for UV or laser procedures. Darker skin tones, for example, may have a higher risk of post-inflammatory hyperpigmentation after certain treatments, so awareness of these risks is essential for choosing products and techniques wisely.
Understanding and applying the Fitzpatrick scale can help guide treatment decisions, manage potential risks, and ensure that skin care is tailored safely and effectively to each individual.
Key Uses in Dermatology & Aesthetics
Skin Cancer Risk Assessment – Lighter skin types (I–II) have a higher risk of UV-induced damage and melanoma.
Laser & Light Treatments – Laser energy settings must be carefully adjusted to avoid burns, pigmentation, or scarring.
Sun Protection Guidance – Determines how much sunscreen protection and reapplication may be required.
Pigmentation & Aging – Darker skin types (V–VI) are less prone to sunburn but more prone to hyperpigmentation, while lighter types age faster due to photodamage.
